The other answers are great, but they always add an ellipsis. The following will only add an ellipsis if the string is too long:
其他答案很好，但它们总是添加省略号。如果字符串太长，以下只会添加省略号：
function truncateText(text, length) {
if (text.length <= length) {
return text;
}
return text.substr(0, length) + '\u2026'
}
let truncated;
truncated = truncateText('Hello, World!', 10);
console.log(truncated);
truncated = truncateText('Hello, World!', 50);
console.log(truncated);回答by Kamil Szymański
Sth like this?
这样的？
var text= "This is your text";
var stripHere = 7;
var shortText = text.substring(0, stripHere) + "...";
alert(shortText);
